Ring size guide

Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.

Measure the inside of a ring that already fits — inner edge to edge — with a ruler in mm, then set it below. No ring handy? Try Measure your finger.

Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.

Method 1 — Use an existing ring

Find a ring that fits the intended finger comfortably.
Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
Enter that measurement in the Measure a ring tab.

Method 2 — Wrap and measure

Wrap a thin strip of paper around the base of your finger.
Mark where it overlaps — measure that length in mm (your circumference).
Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.

Tip: Middle finger sizes typically run half a size larger than the ring finger. If between sizes, go up. Measure in the evening — fingers are slightly larger then.

At a glance

An oval cut lab grown diamond halo engagement ring from Signora Jewels.

A 9.1 × 6.3 mm oval center, approx. 1.50 ct, in a raised prong basket with a single halo and twisted pavé shoulders. Approx. 54 accent diamonds totaling 0.37 ct, with approx. 1.87 ct combined.

Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.

Choose your center diamond weight and metal from the options on this page.

Follow the diamond-set shoulders inward and you'll see two open loops on either side of the oval center. The metal twists around each opening rather than forming a straight band. Signora Jewels pairs that crossover design with a single round-diamond halo, framing the 9.1 × 6.3 mm oval without hiding its elongated outline.

The reference center weighs approximately 1.50 ct. Around it sit an estimated 24 round diamonds weighing 0.16 ct, while another 30 travel along the curved shoulders for 0.21 ct. The pavé stops and starts with the loops, leaving small openings where the polished metal shows through.

Design highlights

Oval cut center diamond, approx. 1.50 ct at reference size
Single pavé Halo with approximately 24 round diamonds
Open crossover shoulders with approximately 30 additional round diamonds
Approx. 0.37 ct of accent diamonds, 1.87 ct combined at reference size
Raised prong-set center basket and open gallery
Customizable 1–4.5 ct center with 11 metal choices

The space inside each leaf-like shoulder loop matters. It separates the two pavé curves, so they read as a twisted pattern instead of one solid strip of diamonds. At the bottom, the band narrows to approximately 1.70 mm. The raised center sits approximately 6.5–7.0 mm high.

About Lab Grown Diamonds

The oval cut spreads its facets across a longer outline, while the surrounding round brilliant diamonds produce smaller flashes of light close to the girdle. All diamonds are lab grown, selected to F color and VS1 clarity specifications. Our diamond and stone guide explains how cut and proportions change the appearance of the finished ring.

Metal, Care & Fit

Choose silver, 9K, 14K or 18K gold in yellow, white or rose, or platinum. The reference image has a warm yellow-metal shank and lighter-toned prongs. The crossover shoulders create small spaces between the pavé curves, so clean those areas gently with warm water, mild soap and a soft brush. Avoid hard knocks to the raised halo and take the ring off before heavy lifting.

FAQ

Does the halo sit around the oval or underneath it?
The single pavé halo surrounds the oval center when viewed from above. It follows the elongated outline of the stone rather than sitting hidden beneath the basket.

Are the twisted shoulders a solid diamond-covered band?
No. Both shoulders form open, leaf-like crossover loops with round diamonds set along the curves. The openings leave visible spaces between the two pavé paths.

Can I select a larger oval center?
Yes. The center diamond is selectable from 1 ct through 4.5 ct, including the reference 1.50 ct. The halo and basket are made to suit the selected center dimensions.

Will this ring sit flush against a straight wedding band?
The raised halo and wider crossover shoulders can leave a gap beside a straight wedding band. A contoured band can follow the profile more closely, depending on its curve and height.

How do I keep the halo and crossover pavé clean?
Use a soft brush with mild soap and warm water, gently cleaning around the halo and through the shoulder openings. These areas collect more residue than a plain band, so avoid abrasive cleaning and check the small prongs periodically.
